One can’t really say since they both have their purpose, but there are definitely pros and cons to bottled water and filtered water.
Using a quality water filtration system for your tap water will give you great-tasting water with high standards. The great thing about filtering your own drinking water is that you know that you’ll get quality water with a quality refining system, you have a reduced carbon footprint since you’re not using single-use plastics, and you save more and more money over time.
On the other hand, each bottled water company has different standards for their respective products. The water pre-treatment has different properties, their treatment methods are different, and their packaging is different. Plastic water bottles are also not environmentally friendly and can leach plastic and chemicals into the water. These factors are why each brand of bottled water has a distinct taste and smell to it.
